Application filed September 21, 1911. Serial No. 650,581.

and more particularly to the class of cool! ing attachments for rotary fans.

The primary object of the invention is the provision of an attachment of this character in which the air, acted upon by the fan, will be subjected to a cooling means, so

as to reduce the temperature of the air, thereby assuring cool breezes during the workin of the fan.

Anot ier object of the invention'is the provision of a cooling attachment of this character in which the rotary fan wheel will be confined within a housing, the walls of which are of foraminous material, preferably of an absorbent character, so that the same may be moistened, whereby the air sucked in from the rear of the fan will be subjected to the moistened walls, thereby assuring cool air currents when thrown forL Ward by the fan wheel, and at the same time freeing the air, acted upon by the fan, from dust and other foreign matter, so as to as'- sure purication of the air when subjected to the action of the fan.

A further object of the invention is the provision of a fan attachment of this character which is capable of being mounted upon varying st les of fans of the rotary type, and that 1s thoroughly reliable and ctlicient in its purpose, and mexpensive 1n manufacture.

`With these and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanylng drawings, and pointed out in the, claims hereunto appended.

In thedrawings: Figure 1 is a front elevation of a fan showing the attachment applied thereto constructed in accordance with theyinvention. Fig. 2 is a vertical longitudinal sectional View of the attachment, showing the fan in side elevation. Fig. 3 is a perspective View of the attachment, the same being partly in section. Fig. 4 is a rear elevation thereof. Fig. 5 is a fragmentary side elevation f a fan showing a slight moditication of cooling attachment applied thereto, the same being partly broken away. F ig. 6 is a vertical sectional view through the attachment, the fan being removed. l? ig. '7 is a vertical transverse sec-- tional view through the attachment.

Similar reference characters indicate cor-A responding parts throughout the several views of the drawings.

Referring to the drawings by numerals, the fan comprises a standard 5 which is of any ordinary well-known construction, 6 the shaft casing, 7 the shaft, and 8 the blades of the fan, the fan being operated either electrically or otherwise in any ordinary well-known manner, and is merely shown for the sake of illustrating the manner of the application of the cooling attachment, forming the subject matter of the present invention, and as will be hereinafter more fully described.

The cooling attachment comprises an upright 9, provided with a sleeve extension 10, medially of its length, the said sleeve being loosely litted about the shaft 7 of the fan, while at the upper end of the upright 9 is formed an eye 1l, through which is passed a water supply pipe 12, the latter being fitted in thc eye in any suitable manner, and is provided with a cut-cti' valve 13, the water supply pipe 12 being connected to a water main or other supply medium (not shown) in the ordinary well-known manner.

Rotatably mounted upon the sleeve is' a hub 14, into which are fitted the inner ends of radially extending hollow perforated arms 15, the outer ends of which are formed with outturned right-angular hollow cups 1G, to which are fixed a pair of spaced annular rings 17 forming a frame supporting a foraminous covering 18, preferably of absorbent material, the covering 1S being disposed upon the frame, so as to close 'the periphery and the inner or rear side thereof, while the forward or outer side `remains open, so as not to impede the air currents driven forwardly by the blades 8 of the fan. The covering 18 is secured to the hollow arms 15 in any suitable manner.

The cups 16, at the outer ends of the arms 15, are provided with inlet openings 19 at their inner sides, so that water may enter and fill the cupsl 16 on the rotation of the frame, whence the said water will be conveyed through the hollow arms 'l5 to .thc

- said. cups being adapted to receive a waterl covering i8 for moisteningthe saine, the

supply `in a manner presently described.

Fixed to the lower end olf the .upright 9 is a water tank or receptacle 20, the lower portion ot the :tramebeing partially sub'- rnerged in the body. et -water contained within the tanker receptacle 20, so that on the rotation ot' the trame, the cups 16 supmerged in the body oi" water will become hlled, andtheir contents-,delivered to the covering 1S for 4the moistening thereof,-so

that the air suclred in atthe rear of the lian lwilllo'e drawn through the covering 18 while moist, lthereby' cooling the air when torced forwardly from the tan, thereby assuring a reduction in the tempera-ture oit the air, and at the same time removing dust and all other' foreign matter therefrom, so that the I maintaining the air at a cool temperature,

airl will bepuritied when being circulated bythetarn c Fixed to the tree end oi the water supply A'pipe/l2, above the frame ot the cooling attachment, is an arcuate-shaped perforated spraying key or head 2l, so that water emitted therefrom will be sprayed onto the covering lBatt-he periphery ot the :trame for the moistcning ot' the said coveringu lt is, of course, understood that the water tank 4or rece-ptacle 20 may` be entirely dispensed with, liit desired9 but should this be the case, the spray ci water trom the water .supply pipe l2 will haveJ to be directed both at the Yperiphery and at the rear oit the trarne tor the moistening otthe'covering' ld thereon,

Disposed circumferentially ot the frame oit the cooling attachment and'ned to the outer sides of the water cups is a toothed gear' 22, meshing with a pinion 23 lined to a shaft 2t5 the same being operated through the medium of a motor, or directly from the shaft 7 of the tan, although the said' sha-:tt 2d may be operated in any' desirable manner, so that the 'frame of the cooling attachment will continuously rotate i at a slower speed than the speed ci rotation ot the tan, during the working.tlhereoto l llt is evident that' the covering i8 on the rotary trame ot the'cooling attachment will be continuously sustained rnoist 'during` the working of the fan, so that the air will be subjected to a cooling medium, lthereby and at the vsametime,rendering it free trom dust and foreignmatter, thereby assuring v rpurineation of the air while the tan is in operationu ln Figa 5, 6 and there is shown a slight modication ot the invention, wherein the cooling attachment comprisesa trarne,

including spaced front and rear annular perforated tubes 25 and 26, respectively,` the same united by means of spaced pertorated cross tubes 27 which are brazed or otherwise secured thereto for establishing ,whereby such air will become cooled priorto y'ico intens? communication with each other, so that water may freely circulate through the tubes; Disposed within the inner tube 265 at the l rear end of they trame, is a convoluted' or spirally arranged hollow perforated tube 28, the outer end oit which is brazed or otherwise secured to the inner tube 26 at a suitable point thereof tor direct communication therewith, while the inner end of the tube 28 is connected to and closedyby means of a bearing1 or sleeve extension 29 formed on' the brace bar 30, the same being. haed to the inner annular tube 26 in any 'suitable manner; 'llhe sleeve or bearing 29 is adapted to surround the shaft 7 et the tan 5, 8O

` through thetubes 25, 26, 2'? and' 28 will percolate ontothe covering 32, saturating the same to render it moist/cned, so that-the air sucked-.in trom' the rear of the .tan will be subjected to the' .moistened .covering1 '1 32,

its. being blasted forwardly from. the fan.

The brace bar 30 is extended upwardly a distance beyond the uppermost point ofthe trame to' term a bearing eye 3d, through which is trained the water' supply pipe provided with ythe usual cu't-,odi-valve 36, said pipe lo -beingconnected thi-ou h the medium ot al lumion 37 with one of t e cross tubes 27 'for communication therewith, so that water -conveyed through the pipe 35 will be. distributed through the tubes 25, 26, 27, and 28, whence thev said'water will be -percolated onto the coverin 32y for the moistening thereof, and in t is vmanner the air acted upon by the fan will-becme cooled prior to the circulation thereof by the'said fan, thus reducing the temperature ci the aira What is vclaimed 'ist l,- 'llhe combination with-a portable fan having a rotary bladed wheel, ot a cooling' imv attachment, comprising a frame formed of a plurality of perforated tubes ,at the periphery and rear et the wheel and supported bythe axis of said wheel and receiving the same whereby the said wheel will be located wholly within the' frame, a surface closing the frame at the periphery and at the rear thereof and adapted to receive moisture, and means for moistening the said surface.
